Question

Explain a person walking past a railway line, in the middle of night hears a ringing sound along with the sound of his footsteps.

Short/Brief Note

Solution

When the vibrations produced by the feet of the person are impressed on the rails, they vibrate with forced vibrations, thereby producing a loud sound.
